Allow different timeouts per request.

[3rd-Eden]

Currently it's only possible to set a timeout option for the whole client instance and it needs to be really high as deployments and start operation can take various of minutes. But other API calls such as a simple account details call will also be under that same timeout and having a timeout of 8+ minutes will be to damn high for it. As you want to be able to timeout those requests in timely manner.

Suggested API's

// if there are 2 objects in the arguments assume that the last one is options for the request
client.command('username', data, options, callback)

or something signature breaking

client.timeout(5000).command('username', data, callback)
